Destroying data on a tablet
I have a tablet (Gemini Joy Tab) that has stopped working and I intend to get a replacement under the extended warranty policy that covers it but I'm concerned that the confidential data contained in the tablet could be accessed by third parties after I hand it over.
I'm sure the retailer (Staples) will give me guarantees that the tablet will be either destroyed or the data contained within made inaccessible but we all know such assurances can be worthless if their is a dishonest person someone in the chain who is determined enough to get at the data. My question is can I do anything to ensure the data is destroyed before I hand the tablet over? As I cannot open the unit to gain access to the components as doing so would invalidate the replacement policy, could I use some form of external energy source to do so i.e strong magnetic field. Any advice would be welcome. Thanks |

Just do a factory reset. That will wipe all the data from the tablet.

Its the same with hard drives, you can delete the data, however the data is still there, its only the FATs/MFTs just get reset so it doesnt know that some data is present on a certain sector onthe disk. If you really are worried about data, burn the bloody thing. Its the only way to be sure. |

Turn on data encryption first and THEN reset it! |

The article I pointed to actually GAVE a more sensible answer!
Turn on data encryption first and THEN reset it! However I do agree having encryption turned on is better than burning your phone.

True, but if you turn on data encryption, you then have to enter a pin when you reboot your phone. Forget that and all your data is gone.

The original question was how to securely erase a tablet which was being returned. So encryption would only need to be turned on just once to do that surely.
